This reminds me of a time long ago when I decided to try a tri-amped setup in my then new Merc 300D wagon. It was when bi and tri amped systems were first being installed in cars. The system involved door and dash mounted tweeters, mids in all doors at lower levels (from the floorboards) and a double sub system that I was able to fit under the floor in the rear of my Mercedes wagon.
I was nonplussed, and somewhat dismayed to hear the first tryout of the door and dash speakers because they seemed to lack the full bodied sound I hoped for. I hadn't hooked in the subs, but with all those six 6 1/2" woofers, where was my sound?
When the entire system was finished with the subs were aboard with their amps I learned about the magic of a sophisticated crossover setup. The 6 1/2" drivers were not woofers at all!
Now, when I first looked at the product sheets of these Pioneers I saw that only one crossover point is listed for each speaker and it was at a level to keep low notes minimized. It dawned then that all of the towers and bookshelves were not to be full range speakers but instead they'd been concieved to supply the middle and high ranges in concert with a subwoofer to supply their missing bass. They aren't meant to be seperate speakers - all five are meant to be as one system, or a multi-location single speaker, or something like that. It's just like my old car system in a way. (Whether the Pioneer sub is adequate to my taste is yet undecided)
With this in mind, I thought, it would be silly to compare the sound of single elements of this Pioneer effort against any speaker set up as a full range speaker. After all, even the lower priced Receivers today are using seperate amps for their output channels and giving us Audyssey onboard to make it work in most any room. Why not take advantage of it instead of muddying up the room with all parts of the sound coming from everywhere out of speakers still designed as two channel stereo full range pumpers?
